The following buttons compute and allow the exchange of match support.
It is possible to use a number of them, and each of them more than once.
Each uses the cost options (above) to determine which currently stored
support values to accumulate.

ordered. Use dynamic programming to set match strength of each
match. Matches not included in the optimal cost path have strength set to zero
otherwise they are reset to default matching strength.

string tot. Accumulate support along globally matched edge
strings and set matching strength of each included match.

figural tot. Accumulate match support figurally along edge strings
in the left image and set string matching strength of each match. Figural
support ofr each match is detemined from the combination of support flowing
in each direction along the left edge string from near neighbour compatible
matches. Where compatibility is determined by disparity and disparity
gradient limits.
